Why Do Preschool STEM?
Why should you do preschool STEM activities?
The answer will change slightly depending on if you’re a teacher or a parent.
If you’re a teacher, many schools are implementing STEM education in preschools and daycares because parents are demanding it. These STEM activities are all designed with preschoolers in mind, so why re-invent the wheel?
Use the easy preschool STEM activities and make your job easier by adding these activities to your STEM lesson plans for preschool!

But if you’re a parent, what is the value of doing STEM activities with preschoolers? Many parents don’t have a lot of time to implement complicated activities with their kids, so why make room for STEM activities?
My answer to this question is simple. A preschool STEM activity provides more educational value in more ways than almost any other activity you can do at home with your kids. Preschool STEM activities include elements of:
- Creative thinking
- Logic
- Critical thinking
- Developing processes
- Learning how to follow directions
- Developing patience
- Improving fine motor skills
- Improving gross motor skills (for some activities)
- Increasing spacial awareness
- Independent learning
There are almost no other activities that combine so many elements of both left and right brain thinking. STEM activities are a natural melding of creative and logical thinking patterns, that help young girls and boys learn to use all parts of their brain from a young age.
